If the distribution of data in a process capability chart shows that all of the data appears between the upper and lower speciﬁcation limits, but is concentrated closer to the upper specification limit, then it is likely that:
A) the process is in control and comfortably meets speciﬁcations.
B) the process is in control and meets speciﬁcations, but is in danger of non-conformance because it is not centred in the target value.
C) the process is in control, but capability does not meet speciﬁcations.
D) the process is not in control, because capability does not meet speciﬁcations.
E) None of these responses are correct.

If the data is concentrated closer to the upper specification limit, it indicates a potential risk of non-conformance as the process may not be centred around the target value.
